CHARLES E. SANFORD, OF NEW? YORK, ASSIGNOR TO RICHARD HARPER LAIMBEER,OF BROOKLYN, N. Y.

WATCHMANS REGISTER.

SPECIFICATION forming part of Letters Patent No, 261,388, dated July 18,1882.

Application filed October 1-2, 1881. (No model.) I

To all whom it may concern;

Be it known that I, CntARLEs E. SANFORD, of the city, county, and Stateof New York, have invented a certain new and useful ImprovementinVVatchmens Registers,of which the following is a full, clear, andexact description.

Reference is to be had to the accompanyingdrawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of my improvement, shown with the box-dooropen. Fig. 2 is a sectional side elevation of the same, taken on theline 00 a", Fig. 1, the door being shown closed. Fig. 3 is ascctionalplan view of a part of the same, taken through the line 9/ y, Fig. 2.Fig. 4 is a sectional plan view of a part of the same, taken through theline .2 a, Fig. 1.

The object of this invention is to improve the construction of thewatchmans register for which Letters Patent No. 113,988 were granted toJames Dunning, April 25, 1871, in such a manner that the markerwillchange its position automatically each day, and also in such a mannerthat the door of the register cannot be opened until the time for whichit was set has expired.

A represents a box of convenient size, and which is provided with adoor, B, in front,and is divided into two compartments by a partition,U,placed parallel with the said door B.

in the rear compartment of the box A is placed an ordinary eight-dayclock-work, D, the hands of which are removed and the hourhand pivot Eof which projects through a hole in the partition 0 and has adial-plate, F,

placed upon it, so as to be carried around by and with the hour-handpivot E in its revolution. The face of the dial-plate F is divided intoseven concentric ringspaces, as shown in Fig. 1, which spaces can bemarked with the names of the days of the week, if desired. Thering-spaces of the dial-plate F are divided into twelve equal parts byradial lines, as shown, which lines can be marked with the numerals from1 to 12, consecutively.

To the end of the pivot E, or to a disk or plate secured to the saidpivot, is attached ec centrically apin, G, which at each revolution ofthe pivot E, and consequently once each twelve hours, comes in contactwith a tooth of the gear-wheel H, and turns the said gearwheel throughthe space of one tooth.

The gear-wheel H, is pivoted to an arm or frame, I, attached to theinner side of the door B, and which is made with an offset to bring thegear wheel to a little distance from the door B.

The gear-wheel H is held from being turned any farther than the space ofone tooth by one contact of the pin G by a spring, J, having a wheel, K,pivoted to its free end to rest upon the teeth of the said gear-wheel H.The other end of the spring Jis connected with the frame I by a shortstud, as shown in Fig. 2; or the spring J can be replaced by a pivotedrigid arm and the wheel K held against the gearwheel H by a spring, J,attached to the said arm and to the door B,all as shown in Fig.1.

To the pivot of the gear-wheel H, at the inner side of the saidgear-wheel, is rigidly attach ed a scroll-plate, L, so that the saidscrollplatc will be carried around by and with the said gear-wheel. Theedge of the scroll-plate L is formed of a number of arcs, eachsucceeding are being nearer the pivot of the said plate than the onebefore it.

Upon the edge of the scroll-plate L rests a pin, M, attached to theplate N, which slides up and down upon a bar, O, attached to the door B,so that the said plate will move down as the scroll-plate L is revolved,and the pin M passes successively from one to another of the arcs of thesaid scroll-plate L.

To the plate N is attached a tube, P, which passes through a slot in thedoor B, and has a plate, Q, attached to its outer end, which slides upand down upon the outer surface of the door B.

The plate Q, is made of such a size as to cover the slot in the saiddoor B, and can be plain or ornamented, as may be desired.

Within the tube 1? is placed a pencil-holder, R, the inner end of whichis tubular to receive a pencil, S, and its outer end is squared orrecessed to receive the key T, by means of which the pencil-holder R andpencil S are pressed inward and made to mark the dial F. The pencil S isheld in a horizontal position by passing through a hole in a bar, U, theends of which are bent inward and then outward, and are attached to, theplate N. The pencil S is drawn back after being pushed forward to markthe dial F by a spiral spring, V, placed upon the said pencil, with itsforward end resting against the guide-bar U and its rear endrestingag'ainst the end of the holder R.

If desired, a pin, W,-can be attached to the holder R to enter a spiralslot, X, in the tube P, so that the pencil-holder R must be turned bythe key T to cause the pencil S to mark the dial F. This arrangementprevents the pencil from being pressed inward to mark the dial by anyother instrument than the proper key.

The plate N and its attachments are kept from being raised from theoutside of the door 13 by a spring-pawl, Y, pivoted to the said plate N,and which engages with the teeth of a ratchet-bar, Z, attached to thesaid door B, as shown in Fig. 1.

The doorB is secured, when closed, by a spring-catch look, a, so thatthe said door will be locked automatically when swung shut, and can beunlocked only by a key. The lock ais set out from the door B a little,as shown in Fig. 4, so that a plate, I), can be slipped in between thesaid lock and door to cover the keyhole of the lock and prevent a keyfrom being inserted.

To the outer end of the plate b is pivoted the end of a bent lever, c,which is pivoted to the doorB and is weighted, or has a weight, d, orweighted arm attached to it in such a manner as to turn the said lever cand draw back the plate I) when the upper end of the said lever c isreleased.

In the upper end of the said lever c is formed, or to it is attached, avertical socket, e, in which is adjustably secured, by a set-screw, f, arod,

g. Upon the lower part of the rod g are formed a number of divisionmarks at a distance apart equal to the width of the ring-spaces of thedial F.

To the sliding plate N is attached the inner end ofa rod, h, in theouter end ofwhich is formed an eye to receive the lower part of the rodg. With this construction, as the plate N and its attachments movedownward the rod h slides downward upon the rod 9, and as it passes offthe lower end of the said rod 9 the lever c is released and is turned bythe weight at to draw back the plate b and uncover the keyhole, allowingthe look a to be unlocked and the door B to be opened. Thedivision-marks upon the'rod 9 allow the said rod to be set in such aposition that thelever will be released at the end of one, two, or anydesired number of days.

By using an eight-day clock-work the box will not need to be openedoftener than once a week, when the dial F-cau be detached and replacedwith another dial, and the box again closed for another week.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1. Thecombination,with thehour-hand pivot of themechanism of an eightday clock, projecting through box-partition O andcarrying an end crank pin, G, of the gear-wheel H, having sixteen teethand acted upon by springheld wheel K, the scroll L, rigidly attached towheel H and having its edge divided into sixteen arcs successivelyapproaching nearer to the center, and the vertically-movable pencil-earrying plate N, having the stud M resting on said scroll, whereby thepencil will be daily lowered so as to mark opposite to a different dayof the week, as notated on the dial-plate F.

2. The combination, with the lock aand mov able pencil-carrier N, of thesliding plate I), the weighted lever t, the adjustable gage-rod g, andthe eye-rod h, whereby the key-hole will be uncovered automatically atthe end of a fixed time, as set forth.
